I have the Go and have found it to be very useful. One thing for you to consider though, is the muscle power required to run the fabric and dies through the machine. Since you have RA, you might want to see if someone you know has the Go or the baby Go and would let you try it before you spend the money. It IS a timesaver and a really good idea, just a little too much force required for those of us who need a little extra help. Good luck!
